For a Brayton heat engine with a regenerator (heat exchange), calculate ηth and Wnet (net power output) for the case.

Case: Investigate the effect of heat exchanger efficiency by varying it from 0 to 80% in steps of 20%. For this case keep Tmax as 1400 K and vary pressure ratio from 4 to 24 for each ηHEX value. [only do the initial case of inputs for equation layout].

Given info

• P1 = 100 kPa, T1 = 0°C, ηcomp = 85%, ηturb = 90% (standard case)

• Neglect kinetic and potential energy changes.

• Working fluid is air. Assume it to be an ideal gas with constant specific heats.

• Compressor and turbine are adiabatic.

• The mass flow rate through the engine is 10 kg/s.
